题目内容
12.Just before the English class,I suddenly realized that I __ ___ my English textbook at home.( )| A. | forgot | B. | had forgotten | C. | left | D. | had left |
分析 就在英语课之前,我突然意识到我把英语课本忘在家里了.
解答 答案:D.过去完成时的构成:had+过去分词,表示在过去的某个时间或动作之前就已经发生或完成的动作,也就是"过去的过去".根据"I suddenly realized that"可知"意识到"这个动作是一个过去的动作.又根据"___ my English textbook at home"可知把书忘在家里,这是在"意识到"之前的动作,也就是在过去的动作之前的动作,就要用过去完成时.另外forgotten是forget的过去分词,意思是"忘记";left是leave的过去分词,意思是"把某物落在了哪里",为习惯用法,所以要用left,不能用forgotten,故选D.
点评 首先要掌握过去完成时的构成以及用法,还要掌握forget和leave的区别,然后结合具体的题目,就可以确定正确答案.
